    摘要: A permanent magnetic machine includes a stator body having a first end, a second end, and a plurality of generally radial slots formed therein for accepting a set of windings having a first set of end-turns at the first end and a second set of end-turns at the second end. The stator body has a plurality of channels adjacent to the slots and extending from the first end of the stator body to the second end of the stator body, wherein the channels are configured to allow the flow of a cooling fluid therethrough. A plurality of nozzles in fluid communication with the plurality of channels are configured to spray the cooling fluid onto the first and second set of end turns.

    摘要: An internal permanent magnet machine (“IPM machine”) of the type used, for example, with traction motors and hybrid electric vehicles, includes a rotor having a plurality of equal-sized (e.g., rectilinear) segmented ferrite magnets arranged in one or more layers. The magnets are inserted within rotor slots that are larger than the magnets themselves, such that one or more air gaps are formed adjacent to the magnets in each layer.

    摘要: Methods and apparatus are provided for stator assembly for use with an electric motor assembly. The stator assembly includes, but is not limited to a stator core that has an inner surface and a plurality of stator slots defined in the inner surface. A fractional slot winding having a plurality of conductors is coupled to the stator core. Each stator slot contains a group of the conductors arranged in a radially adjacent configuration. The groups of conductors in each of the stator slots together form a plurality of concentric rings of conductors. The conductors in each mixed group are arranged such that conductors carrying differing phases of electric current are arranged in a radially alternating configuration.
